No Buffer Space Available (maximum Connections Reached )
vote favorite 2 After some time of running fine, one of our Windows XP SP3 machines does not open some(!) new TCP/IP connections anymore. Putty says Network Error: no buffer space available, IE won't open any new connections but e.g. network drive mappings still work, even new ones can be established. netstat does not show more open connections that usual, ping and DNS lookups work fine. Any hints? networking windows-xp socket share|improve this question edited Jun no buffer space available linux 12 '12 at 5:18 mgorven 22.3k43790 asked Apr 13 '10 at 13:14 braindump 128118 Google photo backups was the culprit in my case.

It just happened to me in Win7 64bit. Chrome and Firefox stopped being able to connect to any web pages, windows file sharing stopped working, and WinSCP and PuTTY both gave errors that included the words No buffer space available. Oddly, Ubuntu 10 running under VirtualBox seemed to have no problem making new network connections - maybe it holds a number of network buffers in reserve. To find out what software is leaking network buffers, you need to close programs until the problem goes away. So I started closing programs and trying the WinSCP connection after each program I closed, but the error persisted. Once I'd closed every visible program, I opened Windows Task Manager with Ctrl-Shift-Esc and started killing invisible programs with the End Process button. Be careful - killing some things the system relies on can cause problems, so don't kill anything you don't recognize without researching what that thing is.

I have googled this error and found very little to help me. What buffer space is this? What does recv failed mean? (Is it at all relevant that sql server is running on the same box?) At least I can answer the question what "recv failed". It means that a call to recv failed. recv is one of the basic TCP/IP functions. Doing "man recv" on a Unix box, I see recv, recvfrom, recvmsg - receive a message from a socket As for the buffer space, I assume that there is a shortage of virtual memory somewhere. Maybe because you are not closing connection correcly, or retrieving all data. Or you simply have a memory leak. But I don't know Java, so I don't really have a clue in that part. Whether the presence of SQL Server could matter, SQL Server by default grabs as much memory it can, so it can as much in cache as possible. Then again, it yields memory if another app competes for memory. You could configure SQL Server to use less memory, but my gut feeli
